Polish opening after 1.b4e5

Why are you believing what an engine says after 2 moves?
Your blitz rating is 1047, and your standard rating is 1400. What an engine says doesnt matter. Also...if you dont know "why" an engine has you at -1.05 then why are you basing moves off an engine?

Ahoy!
While the way DeirdeSky expressed himself was not the best, he is essentially quite correct.
Simply put, if you are happy to lose a tempo after only two moves then by all means give 1.b4 2.b5 a shot. Mind you thrusting a single pawn forward without it actually doing much if anything does not exactly achieve much which is why DeirdeSky suggested 1.b4 e5 2.Bb2.
Personally, I do not rate 1.b4 at all. Being a fan of Michael Basman in my early days I used to play 1.b4 often but it was when I read an article by GM Bangiev I decided to give it up.
His suggestion was simple 1.b4 e5 2.Bb2 Bxb4 3.Bxe5 Nf6 and so forth

yianniww, you misread that earlier discussion. You weren't being advised to play b5 as your second move. 2.Bb2 is still the sensible option. The advice was that it was usually better to push the pawn with b5 than to defend it with a3, but when to do this depends on the variation.

If you can't understand on your own that 2.b5 can't be good then you are doing something terribly wrong.
I would recommend you to play something more classic that will allow you to acquire a good understanding in more universal positions but you aren't going to do it so I will show you how to play the Polish opening.
Black's position is the more pleasant.He has good control of the centre , penty of space , and good positions for his pieces but in lower levels nothing of all these matters(I doubt your opponent's will play the best anyway).If you don't blunder you will win no matter what you play and this is a playable position.
this is why you play 4.c4 as advocated by sokolsky. if white allows black to get d5 and c5, he has a small advantage.
2.a3 is actually fine, but 2.b5 is just bad. the problem is , the positions where white push b5 are usually those where black throws a pawn at it (c5 or a5) where white sidesteps and gets more space. the reason is that by doing in this way, white has to pawns to defend b5, but black only has one pawn to offer a trade.

b5? Say gg to your opponent, it looks great for black.

As one that has played the Polish about 250 or 300 times over the board as White, I can tell you that after 1.b4 e5, the move 2.b5 is NOT White's best move. 2.Bb2 is!
After 1.b4 e5 2.Bb2, Black's best is 2...Bxb4, when after 3.Bxe5 Nf6 4.c4 O-O 5.a3 Ba5 6.Nf3 Re1 7.e3 d5 8.Be2 followed by 9.cxd5 and 10.O-O (Many moves can be switched around - you can play 8.cxd5 and 9.Be2, for instance), White is fine! Not better - if you want that you need to play something like 1.d4 - but fine!
